[Bug 1922342] Re: HIrsute live session takes ages to boot on BIOS systems

[José Marinho]

Bad luck!

It does not work.

I mount the resulting ISO ($NEW) as a loop device and inspect the
partition layout with fdisk. Here is the output:


jose at jose-pc:~/Impish_tests$ sudo fdisk /dev/loop34

Bienvenido a fdisk (util-linux 2.34).
Los cambios solo permanecerán en la memoria, hasta que decida escribirlos.
Tenga cuidado antes de utilizar la orden de escritura.

La tabla GPT primaria está dañada, pero la de respaldo parece que está
bien, así que esa será la que se utilice.

But the layout is different from the usb stick burned with that ISO file

Title:
  HIrsute live session takes ages to boot on BIOS systems

Status in casper package in Ubuntu:
  Confirmed

Bug description:
  First of all, I change the description of this bug because, thanks to
  Chris Guiver comments, I could check that the live session effectively
  works but it takes too long to complete. That's why I change the
  description of the bug from live session does not boot to live session
  takes ages to boot. I hope this is the best approach to this.

  I think the problem is the same as described here:
  https://discourse.ubuntubudgie.org/t/20-10-grub-error-can-t-find-
  command-grub-platform/4292. I can see prior to grub menu, briefly, the
  same error: Error can't find grub_platform. After the solution
  described below, this error is not showed and the system is able to
  boot.

  I try making the live usb using startup disk creator and with gnome-
  disks --> Restore disk image and get the same results.

  The live-usb has a gpt partition table instead of mbr like 20.04 live-
  usb has. That implies, I think, that the first one does not boot on
  BIOS systems and the second does.

  I try the same live-usb on an EFI laptop and it boots perfectly
  (perhaps it takes long time, but more less than in this case.

  If I try the solution described here:
  https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1905491/comments/8
  then it works.
